If you only need the dictionary keys <code>1</code>, <code>2</code>, and <code>3</code> use: <code>your_dict.keys()</code>.

If you only need the dictionary values <code>-0.3246</code>, <code>-0.9185</code>, and <code>-3985</code> use: <code>your_dict.values()</code>.

If you want both keys and values use: <code>your_dict.items()</code> which returns a list of tuples <code>[(key1, value1), (key2, value2), ...]</code>.

Pythonic duck-typing should in principle determine what an object can do, i.e., its properties and methods. By looking at a dictionary object one may try to guess it has at least one of the following: <code>dict.keys()</code> or <code>dict.values()</code> methods. You should try to use this approach for future work with programming languages whose type checking occurs at runtime, especially those with the duck-typing nature.

How do I extract all of the values of <code>d</code> into a list <code>l</code>?

How can I extract all values from a dictionary in Python?
